ATTORNEYS United States Patent 3,311,286 CUMBINATION WRAP CONTAINER Charles S. Giacoppe, 49d) Wanoosnoc Road, Fitchburg, Mass. 01420 Filed July 29, 1965, Ser. No. 475,725 2 Claims. (Cl. 229-37) This invention relates to packaging, and more particularly to a combination wrap container for bulk shipment of a variety of products.

An object of this invention is to provide a practical and commercially acceptable die-cut, wrap container of unitary construction providing an economical vehicle for the shipment of goods.

Another object is to provide a wrap container of the character described which may be made from a variety of lightweight to heavy materials including plain, ,reinforced, laminated or saturated papers, in one, two or more plies, or any other acceptable flexible or rigid material that is capable of being folded, scored and cut, and which will provide the necessary protective characteristics.

A further object is to provide a wrap container formed from a blank and including wall panels, the margins of the blank forming the panels being adhered together, and end flaps issuing from the panels adapted to be overlapped and sealed together to complete the container.

Other objects of the invention will be manifest from the following description of the present preferred forms of the invention, taken in connection with the accompanying drawings, wherein:

FIG. 1 is a plan view of the wrap container blank of the present invention;

FIG. 2 is a perspective view of the present wrap container, partially assembled;

FIGS. 3, 4 and 5 are perspective views similar to FIG. 2, illustrating the successive steps of folding the end flaps of the container to form the completely closed and sealed wrap containers;

FIG. 6 is a view similar to FIG. 1, showing a modified form of the present invention;

FIG. 7 is a view similar to FIG. 1, showing another modified form of the present invention;

FIG. 8 is a view similar to FIG. 1 showing still another modification of the present invention; and

FIG. 9 is a view similar to FIG. 1 showing still another modification of the present invention.

Referring now in greater detail to the drawings, there is shown in FIG. 1, a rectangular blank made of paper or other suitable flexible material. The blank is provided with horizontal score lines 11), vertical score lines 11 and vertical cuts 12 for erecting a wrap container in accordance with the present invention. The scored and slit portions thereby form a plurality of central wall panels 13, 14 and of similar rectangular size and lateral panels 16 and 17, adjacent panels 13 and 15 respectively, which are narrower in width than said central panels. The marginal edge of panel 16 is coated with an adhesive 18, for purposes to be hereinafter more fully set out.

The scored and slit portions of the blank additionally provide end fiaps 19,20 and 21 of similar size, which are adjacent the upper and lower margins of panels 13, 14 and 15 respectively. Smaller flaps 22 and 23 are disposed adjacent to, and complement panels 16 and 17 in width. Flaps 22 are provided with marginal adhesive strips 24.

In accordance with this form of the invention, end flaps 19, 20 and 21 are square in shape as is the fiap entity formed when flaps 22 and 23 are overlapped and secured together, as illustrated in FIGS. 2 to 5. Additionally, the length of each side of each flap is the same as the width of the wall panels so that all of the end flaps completely span the open ends of the container, thereby providing four full thicknesses of material and maximum 3,311,285 Patented Mar. 28, 1967 strength at the ends of the wrap container, where the stress is greatest.

In forming the wrap container from the blank shown in FIG. 1, the blank is folded along score lines 11, in the manner illustrated in FIG. 2. Panels 16 and 17 and flaps 22 and 23 are in partially overlapped relationship to permit adherence of adhesive 18 of panel 16 and adhesive 24 of end flaps 22 to panel 17 and end flaps 23 respectively, thereby forming the four-sided wrap container. End flaps I9, 20, 21 and the unitary flap formed by overlapped flaps 22 and 23 are then folded inwardly as shown in FIGS. 3, 4 and 5. The sequence of folding the end flaps to close the end of the container may be varied, if desired. For example, flap 20 may be folded first, flaps 22 and 23 second, flap 19 third, and flap 21 fourth. Securement of the flaps in the closed position may be effected by any suitable sealing means, such as a self-sealing compound that adheres only to itself. If desired, a mandrel may be employed in setting up the wrap container for use.

The type and amount of adhesive, the method of application and size of the coated strip applied to the marginal edges of panel 16 and flaps 22 will be predicated upon size, product, density, etc. In the event that a self-sealing adhesive is to be employed, a strip thereof is applied to the marginal edge of panel 16 and flaps 22 and a complemental strip thereof is applied to the reverse side of panel 17 and flaps 23.

In FIGS. 6 to 9, there are illustrated modified forms of the blank illustrated in FIG. 1. In the modified form of FIG. 6, the parts thereof which are similar to that form shown in FIG. 1 are designated by like numbers followed by the letter It will be noted, however, that in this form, flaps 20a and the flap entity formed by interengaged flaps 22a and 23a completely overlap each other. However, in accordance with this form of the invention, flaps 25 and 26 extend to a point slightly beyond the mid-point of the height of end flap 20a. Consequently when flaps 25 and 26 are folded inwardly, they overlap only at the center of the container end.

In the modified form of FIG. 7, the parts thereof which are similar to that form shown in FIG. 1 are designated by like numbers followed by the letter 1). In this form of the invention, flaps 20b and the flap entity formed by interengaged flaps 22b and 23b completely overlap each other. Inner flaps 27 and 28 are half the height of end flap 20b and when bent inwardly, meet at the center of the end opening.

In the modified form of FIG. 8, the parts thereof which are similar to that form shown in FIG. 1 are designated by like numbers followed by the letter 0. In this form of the invention, flaps 20c and the flap entity formed by interengaged flaps 22c and 230 overlap at the center of the opening and are rectangular. Flaps 29 and 30 are of the same height as flap 200 but are tapered inwardly from the inner to the outer limits thereof and likewise overlap at the center of the end opening.

In FIG. 9, there is illustrated an open end wrap container blank of the same basic construction as employed in the form of invention shown in FIG. 1 with the exception that end flaps are provided at one terminal of the container only, the other end being open. The parts of the container shown in FIG. 9 are identified by the same numbers aplied to FIG. 1, followed by the letter :1.

The various forms of the present invention afford different strength characteristics at the locus of the end Walls and all types of plain, reinforced papers in one, two or more plies, or other suitable flexible material may be used. In addition, rigid material such as solid fibreboard in 0.060, 0.080, 0.090 points or better, double-faced corrugated fibreboard and double-wall corrugated fibreboard may be employed. This affords a wide range of wrap containers from which to choose for providing the necessary protective characteristics to the wrap container. In this way, the choice of the proper type of container and material to effect the necessary protection for a particular type of goods is obtained. Use of too heavy a wrap container is thereby avoided and consequently manufacturing and shipping costs are kept to a minimum. The present invention further lends itself to ready imprinting of designs and informational data thereon which enhances the sales appeal of the container.

The blanks embodying the various forms of the present invention are readily die-cut by virtue of the blank shape requiring no exotic cutting or locking tabs to set up the container. Wrap container blanks of the present invention are readily shipped and stored in sheet or other acceptable form on pallets or skids and may be quickly set up for use by means of conventional automatic equipment, if desired. While the present warp container is particularly adapted for directly holding goods to be shipped, it is understood that it is equally capable of use as an external container for goods already packaged. Various other changes may be made within the scope of the claims hereto appended.
